Especially, the utility model discloses a current conversion portion 12 provides the DC power supply who is fit for the charging of smart machine 20, and according to the charging method and provide quick charge with H and slow charging with L DC power supply.

The supply of the H DC power supply for fast charging is an initial value, and the L DC power supply for slow charging is an initial value.

Preferably, the initial value is switched by the control unit 14 using another selection switch or selection contact.

It is generally known that fast charging consumes more power than slow charging, and also shortens the battery life of the smart device 20.

The current converting unit 12 includes two secondary coils and includes other boosting or voltage-reducing circuits, and thus provides a dc power supply for fast charging H and slow charging L as necessary.

The current conversion unit 12 supplies a dc power to the cable connection unit 13 via the switch unit 15, and supplies a current to the smart device 20 connected to the cable 30 connected to the cable connection unit 13 to perform charging.

At this time, the cable 30 uses a USB OTG cable. I.e. the connection of data and power can be made.

The switch unit 15 has a plurality of contacts, and supplies the current of the current converting unit 12 to the cable connecting unit 13 or the power supply cutting unit 11 cuts the AC power supply AC and receives the battery power of the smart device 20 supplied through the cable connecting unit 13 to supply the power to the control unit 14 according to the control of the control unit 14.

The cable connection portion 13 is capable of bidirectional power supply and data transfer, and is used for connection with the USB OTG cable 30.

The operation of the present invention will be described below, taking a more specific example of standby current interruption as an example.

When the smart device 20 is charged, the current converting unit 12 converts the AC power supply AC into the dc power supply without disconnecting the power supply interrupting unit 11.

At this time, the switching section 15 has a switching state in which the current of the current converting section 12 is supplied to the cable connecting section.

The smart device 20 is connected to the cable connection unit 13 via a cable 30, and is charged.

The utility model is used for under smart machine 20's the complete charging state, cut off and supply alternating current power supply AC to battery charging outfit 10, and establish standby power consumption into 0, should be able to detect smart machine 20's the degree of charging.

The charging degree of the smart device 20 confirms the state of the power module of the smart device 20 according to the execution of the dedicated application program provided in the smart device 20, and when the charging rate is 100%, data informing of the full charge state is transmitted through the cable 30.

The data of the cable 30, which is notified of the fully charged state, is received with the control unit 14 through the USB OTG cable 30 and the cable connection unit 13.

The control unit 14 switches the operation mode to the slave mode, and controls the switching unit 15 to switch the battery so that the battery power of the smart device 20 is supplied to the charging device 10.

Therefore, the control unit 14 controls the power cut-off unit 11 to cut off the application of the AC power supply AC in a state of power running by the battery of the smart device 20, thereby completely cutting off the standby power consumption.

The user keeps the state of the control unit 14 and the power shutoff unit 11 in a state where the cable 30 is pulled out from the smart device 20.

When the user connects the smart device 20 to the cable 30 to charge the smart device 20 again, the control unit 14 is in the slave mode, the control unit 14 at the time when the battery power of the smart device 20 is supplied to the control unit 14 releases the cut-off state of the power cut-off unit 11, controls the switch unit 15, supplies the current of the current conversion unit 12 to the cable connection unit 13 through the switch unit 15, and charges the smart device 20 through the cable 30.

As described above, although the case where the control unit 14 recognizes the charging state of the smart device 20 in the application program of the smart device is described, the configuration of another embodiment of the present invention shown in fig. 2 further includes the power detection unit 16, and after the charging state of the smart device 20 is confirmed, the power cutoff unit 11 and the switch unit 15 are switched to be operated.

The general smart device 20 has a cut-off circuit for preventing overcharge, and when the cut-off circuit is operated, the power supply detecting portion 16 detects a change in the charging current when the charging current changes, so that the control portion 14 recognizes that the smart device is fully charged.

Therefore, the utility model discloses use the USB OTG cable and improve compatibility to be applicable to various forms of smart machine, through data transmission and reception or the charged state between detection smart machine 20 and the control part 14, and confirm the cut-off time point of power supply cut-off portion 11.

Further, the switching to the supply state is automatically performed in the power-off state at the next charging, and therefore, the battery pack has a feature of being easy to use.

As another feature of the present invention, the charging mode is automatically changed according to the setting of the user, the charging habit, or the time to start charging.

An example of the transformation as described above is explained in more detail as follows.

Fig. 3 is an exemplary diagram of an application screen 21 provided in the smart device.

The user sets the charging time using the application program and directly selects the charging mode.

In the case where the charging time is set to be within one hour, in the application program of the smart device 20, data requesting a quick charge is transmitted through the cable 30, and the control unit 14 controls the current conversion unit 12 to supply the H dc power for quick charge through the switch unit 15, the cable connection unit 13, and the cable 30, thereby charging the smart device 20.

In the case where the user sets the charging time to be within two hours, the control unit 14 controls the current conversion unit 12 to output the H dc power for quick charging for a certain time (for example, 30 minutes) and then output the L dc power for slow charging, as necessary.

When the charging time is sufficient for two or more hours, the user selects two or more hours on the application screen 21, and the control unit 14, which receives a corresponding command through the USB OTG cable 30, controls the current conversion unit 12 to output the L dc power for slow charging, thereby performing slow charging of the smart device 20.

The application program confirms the connection state of the cable 30, and thus confirms the charging habit of the user.

For example, the cable 30 is connected as needed, and whether or not there is a habit of releasing the connection or a habit of charging for a long time is detected, and the habit of the user is confirmed by detecting the connection and disconnection time of the cable at ordinary times, and a charging method conforming to the habit is provided.

The smart device 20 of the user having the long-time charging habit performs the slow charging all the time, and the smart device 20 of the user having the short-time charging habit controls the current converting part 12 to perform the fast charging.

At this time, the charging habit of the user is detected by the application provided in the smart device 20 and detected by the firmware of the control unit 14.

Even in the charging as described above, when the smart device 20 is in the fully charged state, the AC power supply AC is cut off by the power cut-off unit 11.

Then, the sleep mode, the fast charge, and the slow charge are selected by an application provided in the smart device 20, and the control unit 14 controls the charge according to the respective modes.

In general, in the case of charging during sleep time, it is assumed that the user sleeps and charges at 23 o 'clock, and in the case of getting up at 6 o' clock and separating the cable from the smart device 20, the time of 7 hours is not required for charging the smart device 20, and therefore, the time can be divided according to the setting to control various kinds of charging.

Fig. 4a shows an example of the charging start and charging end times, and fig. 4b shows an embodiment of charging control performed by the control unit 14.

The control unit 14 operates in the slave mode from 23 to 01 at the initial charging stage, and controls the smart device 20 not to be substantially charged while keeping the power shutoff unit 11 in the shutoff state.

After point 01, the control unit 14 releases the power cut-off state of the power cut-off unit 11 to supply the AC power to the current converting unit 12, the control unit 14 controls the current converting unit 12 to output the slow charging L dc power, switches the switching state of the switching unit 15, and supplies the current to the smart device 20 by performing the slow charging through the cable 30.

The slow charging state is maintained up to point 04, and the smart device 20 is switched to the off-standby state even if it was in the fully charged state before.

After 04, the system shifts to a shutdown standby state.

For the off standby state, the control unit 14 controls the switching unit 15 to receive the power of the battery of the smart device 20 supplied to operate, and makes the power supply cut-off unit 11 into the off state to prevent the standby current from being consumed.

That is, during the operation standby period of the control section 14, the current supplied to the control section utilizes the current of the battery of the smart device 20.

Fig. 4c shows another embodiment of charge control.

In the initial charging state, the control unit 14 sets the smart device 20 to the slow charging mode and sets the smart device 20 to the slow charging mode, or if the set time is exceeded, the control unit 14 keeps the off-standby mode and controls the current conversion unit 12 to perform the quick charging mode before the charge release time.

The above-described procedure is understood to be a case where the battery is charged again when the standby power is supplied to the control unit 14 by the battery of the smart device 20 that is fully charged and the charging rate of the battery is reduced.

Therefore, the utility model discloses can carry out various charging control automatically according to setting for can carry out various controls to be used for user's needs or the minimizing of power consumption or prevent to shorten the life-span of battery.
